Once you insert your image the first time, it gets easier to do. You just have to get over that initial hump of confusion, fear and excitement. Next thing you know, you will want to insert an image every day. Multiple times a day even. Just be smart about which posts you insert an image on. Take your time with a post before you commit to inserting an image.

I'm still using imgur, it's free, no watermarks and you can make posts private (such that only those with the link or direct links to images in threads can access them). Easy to use on my phone or computer.
